If report of KHIVA is of enemy submarine it would indicate that another cruiser submarine is at sea.1 A second cruiser submarine has been due to come out for several weeks but thus far no information has been obtained. Were any U.S. submarines in vicinity of KHIVA at time reported. 204 <15026>

Source Note: Cy, DNA, RG 45, Entry 517B. Sims reported later in the day that he still had “no reliable information” on Khiva’s supposed sighting. Sims to Opnav, 26 June 1918, DNA, RG 45, Entry 517B.

Footnote 1: The U-156 departed from Kiel on 15 June and sank a British steamer on 26 June. It is likely this was the submarine reported in this cable. See, Clark, When the U-Boats came to America: 156-157.
